Józef Robakowski is a key creator of pragmatic conceptualism in the 1970s. He rejected essentialist definitions of art and focused on new qualities emerging from matter, language, context, and technology. His work "Kat Energetyczna" (Energy Angle) reflects a postmodern gesture that distances itself from one meaning while seeking an intensive experience of contact. Robakowski emphasized being a careful observer, interested in common sense in reality, and highlighting important issues in an original way.
